Solution for 110=0.1x(30-x) equation:


Simplifying
110 = 0.1x(30 + -1x)
110 = (30 * 0.1x + -1x * 0.1x)
110 = (3x + -0.1x2)

Solving
110 = 3x + -0.1x2

Solving for variable 'x'.

Reorder the terms:
110 + -3x + 0.1x2 = 3x + -3x + -0.1x2 + 0.1x2

Combine like terms: 3x + -3x = 0
110 + -3x + 0.1x2 = 0 + -0.1x2 + 0.1x2
110 + -3x + 0.1x2 = -0.1x2 + 0.1x2

Combine like terms: -0.1x2 + 0.1x2 = 0.0
110 + -3x + 0.1x2 = 0.0

Begin completing the square.  Divide all terms by
0.1 the coefficient of the squared term: 

Divide each side by '0.1'.
1100 + -30x + x2 = 0

Move the constant term to the right:

Add '-1100' to each side of the equation.
1100 + -30x + -1100 + x2 = 0 + -1100

Reorder the terms:
1100 + -1100 + -30x + x2 = 0 + -1100

Combine like terms: 1100 + -1100 = 0
0 + -30x + x2 = 0 + -1100
-30x + x2 = 0 + -1100

Combine like terms: 0 + -1100 = -1100
-30x + x2 = -1100

The x term is -30x.  Take half its coefficient (-15).
Square it (225) and add it to both sides.

Add '225' to each side of the equation.
-30x + 225 + x2 = -1100 + 225

Reorder the terms:
225 + -30x + x2 = -1100 + 225

Combine like terms: -1100 + 225 = -875
225 + -30x + x2 = -875

Factor a perfect square on the left side:
(x + -15)(x + -15) = -875

Can't calculate square root of the right side.

The solution to this equation could not be determined.
